Toledo Regional ITS Architecture Update (Final)

Element Expanded Functional Requirements: MDOT Statewide Center

Functional Area: TMC Freeway Management
  1. The center shall remotely control systems to manage use of the freeways, including ramp, interchange, and mainline metering.
  2. The center shall collect operational status from ramp meters, interchange meters, and mainline meters and compare against the control information sent by the center.
  3. The center shall collect fault data from ramp meters, interchange meters, and mainline meters.
  4. The center shall implement control strategies, under control of center personnel, on some or all of the freeway network devices (e.g. ramp meters, interchange meters, and mainline meters), based on data from sensors monitoring traffic conditions upstream, downstream, and queue data on the approaches to the meters.
Functional Area: TMC Regional Traffic Control
  1. The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
  2. The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).
Functional Area: TMC Signal Control
  1. The center shall remotely control traffic signal controllers.
  2. The center shall accept notifications of pedestrian calls.
  3. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
  4. The center shall collect traffic signal controller fault data from the field.
  5. The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
  6. The center shall implement control plans to coordinate signalized intersections based on data from sensors.
  7. The center shall manage boundaries of the control sections used within the signal system.
  8. The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
Functional Area: TMC Toll/Parking Coordination
  1. The center shall collect and store toll pricing data from toll administration centers, including the price for each road segment to which a toll applies, with the time and date for when it applies.
  2. The center shall collect and store parking information from parking management providers including lot locations, features (e.g. ability to handle oversized vehicles), capacity, type, hours of operation and rates.
  3. The center shall collect and store transit fare and schedule information from transit management centers.
  4. The center shall collect and store current transit, parking, and toll fee schedule information provided by regional traveler information systems.
  5. The center shall send requests to toll administration centers to change pricing, modify restrictions, or modify operations of a toll road facility.
  6. The center shall send requests to parking management providers to change the current parking lot charging structure.
  7. The center shall send requests to transit management centers to change the current transit services - schedules or fares of the transit services including park-and-ride lots.
Functional Area: TMC Traffic Network Performance Evaluation
  1. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center to support overall network performance evaluations.
  2. The center shall collect wide-area pollution data from emissions management centers to support overall network performance evaluations.
  3. The center shall collect and store plans from event promoters for major future events possibly impacting traffic to support overall network performance evaluations.
  4. The center shall collect and store anticipated route information from information service providers to support overall network performance evaluations and predictions.
  5. The center shall exchange information with transit management centers including details current transit routes, the level of service on each route, and the progress of individual vehicles along their routes for use in forecasting demand and estimating current transportation network performance.
  6. The center shall exchange traffic information with other traffic management centers, including incidents, congestion data, traffic data, signal timing plans, and real-time signal control information to support overall network performance evaluations.
  7. The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for network performance evaluations.
  8. The center shall provide an interface to the archive data repository to enable the operator to retrieve historical operating data for use in planning to predict future traffic patterns and conditions.
  9. This center shall use the collected information to measure overall current and forecast network performance and predict travel demand patterns.
